What’s a Dual Mass Flywheel (DMF) and Dual Mass Flywheel Replacement (DMR)?

A Dual Mass Flywheel (DMF) is comprised of two flywheels that work together with dampening springs to reduce vibrations.

ADVANTAGES

– Isolates engine vibrations
– Reduces noise
– Helps to prevent transmission damage
– Improves shifting comfort

Dual Mass Flywheel Replacements (DMR) also known as a Solid Mass Flywheel (SMF) move the damping system from the flywheel to the clutch plate. This returns the flywheel back to a conventional solid mass flywheel.
Advantages (over DMF)
– Greater reliability
– Better thermal dynamics
– Cost efficient: Both on the initial purchase and ongoing with the ability to machine the flywheel.
Note: When a DMR system is fitted can have an increase in drive train noise.
